The 2.3L EcoBoost's factory tuning leaves plenty on the table for 5-Star to work with and really transform your Ranger. The average baseline power output of 5-Star's test truck at stock 93 octane was about 256 horsepower and roughly 281lb-ft of torque. With 5-Star's powerful 93 octane Performance tune, that same 2.3L EcoBoost truck put down an average of 312 horsepower and 369lb-ft of peak torque. That's a gain of 56 horsepower and 88lb-ft of torque over stock at peak increase. Most impressively is that the maximum gain in peak torque took place at 3450rpm, where stock torque sat at a measly 281lb-ft, giving you a big bump in pulling power and off-the-line performance without the turbo lag and hesitation of the factory tune. In additional testing, the tuned Ranger performed a 0-60 MPH test in only 5.49 seconds while the stock clocked in at a significantly slower 7.44 seconds with the same test conditions and constraints. The power gains are paired up with greatly overhauled transmission shift points and shift pressures which take most of the sluggishness out of your 2019-2021 Ranger and let you really enjoy its improved power output.
